Google’s Sycamore quantum chip breaks classical computers performing random circuit sampling

Phase transition in linear cross-entropy. Credit: Nature (2024). DOI: 10.1038/s41586-024-07998-6 A team of engineers, physicists, and quantum experts at Google Research found that by reducing noise to a certain level, the company’s Sycamore quantum chip can outperform classical computers that perform random circuit sampling (RCS). discovered. In their study published in the journal Nature, the group fine-tuned the processor’s operating…
